【摘要】 利用带活性羟基的N-取代3,4-富勒烯吡咯烷作为引发剂,引发ε-己内酯开环聚合,制备了一种具有新型结构的富勒烯末端封端聚己内酯,通过核磁共振(1H NMR,13C NMR)、红外光谱(FTIR)和基质辅助激光解吸电离飞行时间质谱(MALDI-TOF-MS)等手段对产物进行了结构表征,并用热重(TG)分析和差示扫描量热(DSC)分析的方法进行了热学性能分析.结果表明,与聚己内酯相比产物热稳定性增加.更多还原

【Abstract】 Using N-substituted 3,4-fullero pyrrolidine with an active hydroxyl group as an initiator,polymerization of ε-caprolactone was performed via ring-opening polymerization. The product was characterized by 1H NMR,13C NMR and MALDI-TOF MS and its thermal properties were determined by TG and DSC. The results show that a fullerene end-capped poly(ε-caprolactone) is achieved,and the product is more thermally tolerative than poly(ε-caprolactone).更多还原
